Paper Session 1: Sustainable Development

Application of GIS in communicating environmental impact of development projects in

Kenya: A case study of LAPSET oil and gas corridor Samoei Emmanuel & Maina Cecilia Department of Community Development and Environmental Management Cooperative University of Kenya P.O. Box 24814 -00502 Karen, Nairobi Environmental impact assessment (EIA) is a key requirement for any sustainable development project,

the World Bank through its development partners, advocate for a full inventory of all environmental and

social impacts before funding and implementation of any proposed development programs. Kenya, as the

rest of the world, is at the forefront in implementing environmentally sound development programs, this

is also in line with its development blue print Vision 2030 of integrating green development technology in

Kenya. Recently, Kenya discovered oil and gas deposits on its Nothern and coastal regions; specific

deposits of oil in Turkana (Ngamia 1, 2) and Mandera counties while gas deposits found in Lamu and other

offshore (the sea) sites. These discoveries have prompted the government to initiate programs to

facilitate extraction and transport of oil from source to market. One such project is The Lamu Port South

Sudan Ethiopia Transport (LAPSSET) corridor, which encompasses a seaport, pipelines, railways/road

networks, airports and urban development from Lamu through Lodwar to South Sudan and Ethiopia.

Unfortunately, it is not obviously deductible the full extent of the negative environmental impacts of this

mega project which is almost at implementation. Using GIS technology, we show the geographic

impression and coverage of the project, the possible environmental hotspots to be affected, the spatial

extent of the impacts and any possible displacement on communities. This research used the the gazetted

oil block coordinate 5th edition schedules in the Kenya Gazette Notice No. 334 Cap 308 of May 2016 (Vol.

CXVIII -No.52). These coordinates were overlaid on existing basemaps and landuses including protected

areas and the proposed corridor using Arc GIS 10:3.5 available at CUK through ESRI granted licence. The

output displays over 10 useful maps showing specific impact areas and affected communities both

onshore and offshore, the researcher also presents possible recommendations and alternatives against a

severe impact observed. This information is very useful by the government and other development

partners in evaluating project impacts as well as in making environmentally oriented decision-making.

Key Words: EIA, LAPSSET, spatial, oil and gas, sustainable development

Use of Borrowed Landfill Siting Criteria and GIS in Assessing the Appropriateness of an

Existing Dumpsite and the Suitability of Future Landfill Sites for Nairobi Justin Gichobi Kimani Pwani University Email: j.kimani@pu.ac.ke, Tel. 0722 333 998 According to the Nairobi County Annual Development Plan (2017/2018), the City generates approximately 2,400 tons of solid waste per day. Numerous waste minimization strategies have been put in place, which have not been successful in reducing the amount that needs to be disposed of at a landfill site. This results in mounting pressure on the existing dumpsite thus necessitating the need for a new landfill. The construction of a landfill has significant impacts on the environment, which are directly

related to the physical location of the project. Siting a landfill is one example of a spatial problem where set out guidelines can be expressed spatially in order to achieve the objective. This paper presents results of a spatial analysis of suitable sites using guidelines borrowed from the Department of Water Affairs and Forestry, South Africa. The environmental criteria and GIS were used to evaluate the suitability of the existing and future sites for locating a landfill for Nairobi County. The research findings indicate that Nairobi does not have a suitable site for locating a landfill. In addition, the findings demonstrate that GIS is an efficient tool that can be implemented in landfill site studies that expedite decision making.

Development of a spatial decision support system that integrates a mobile field

geospatial data collector and web-based mapping tools for a systematic way of recording

and visualizing the collected survey data of Avocado farms Maina Cecilia Department of Community Development and Environmental Management Cooperative University of Kenya P.O. Box 24814 -00502 Karen, Nairobi

Agriculture dominates Kenya’s economy and almost three quarters of the country’s workers make their

living by farming. But nearly one half of its agricultural output is for the farmers’ own subsistence: Kenya’s

small farmers have difficulty selling their products because there are few reliable markets.. Without the

ability to sustainably market their produce, many small farmers are trapped in a cycle of poverty as

brokers turn up with offers to buy smallholders’ produce while others simply watch as their fruits fall on

the ground and their trees wither. New Zealand-based Olivado Group expanded into Kenya in 2007 in

order to purchase avocados directly from small farmers to meet the fast-growing demand for its oil. In

the process, the company created a unique inclusive business model involving a Fair Trade and Organic

out-grower scheme of 1,500 Kenyan farmers – more than half of them women. In 2010 olivado built a

factory in Murang’a, near Thika. With 1,350 small farm holdings now certified organic and supplying us

with avocados, olivado has a capacity in Kenya of 900MT of organic extra virgin avocado oil per year.

Olivado vision is to work with over 7,000 smallholder producers in Kenya and Tanzania by 2021. In bid to

effectively achieve this vision, improving the current paper based data collection and inspection process

is vital. Some of the challenges of this paper-based process include; - Arduous process of changing farmer’s

details and Interpreting handwritten notes could cause incorrect data being entered. This research

therefore invented a GIS integrated mobile data collection solution that will enable to streamline the data

collection process and make the inspection procedure as quick and simple as possible for the trained

Olivado inspectors in order to reach out to more farmers. The mobile solution can be linked to a

centralized farmer information system to form a platform with a secure environment to record, store,

analyze and generate reports on the inspections. The aim of platform is to provide a holistic year-round

yield monitoring, farm data collection, entry; storage and mid-season analysis to enable appropriate

harvest planning, monitor crop health as well detect threat or risk associated with the farms such as pest

and diseases. This paper presents the technology under research, its application potential, and possibility

for up scaling.

Cholera Prevalence in Kenya- Lilian Cheruto Cholera Prevalence in Kenya Lilian Cheruto Kipchumba Kenyatta University EMAIL: cherutolil@gmail.com Kenya has previously experienced an upsurge in the number of cholera cases reported. It is therefore of

essence to understand the scope, spread and impacts of the disease. The presentation adopts use of ESRI

Story maps templates to give a brief on the history, occurrence, management as well as giving

recommendations on how to curb the disease. The story map template offers an easy, yet dynamic and

interactive way to convey the narrative information; with the combination of maps, images and videos.

The presentation maximizes on the ArcGIS desktop, ArcGIS Online and ESRI Story Maps Templates to pass

across information. Using secondary data sourced from the Ministry of Health, and the World Health

Organization (WHO) the tabular data was converted into spatial data using ArcGIS Desktop 10.5. The data

was thereafter uploaded to ArcGIS online platform, to create web maps. The story map is created using

the cascade template. The story map has combined web maps, narrative text and multimedia to convey

the information about cholera prevalence and its occurrence in Kenya. The story map also gives

recommendation on how to curb the disease.

Geographical indications: GIS informs goat meat differentiation in Baringo, Kenya Maina, FW and J Mburu PhD Student Department of Agricultural Economics, University of Nairobi

Differentiating products based on characteristics inherently attributable to the geographical region of

origin (geographical indications) is perceived as a potential differentiation strategy in agricultural

marketing contributing to environmental conservation. Cultural practices carried on over years also

manifest in the product quality preferred by consumers. Identification of potential geographical region

from which such products are uniquely produced requires projecting socio-economic characteristics onto

biophysical maps. The objective of the study was to map socio-economic characteristics of Baringo goat

meat producers onto various biophysical maps in order to identify the source of uniqueness and hence

form a basis for protecting the goat meat as geographical indications for marketing purposes. Goat meat

from specific regions in the county is reputed to be naturally salty. Socio-economic data including

producer perceptions on the source of uniqueness was collected through household surveys of at least

136 georeferenced households. Using ArcGIS, the resulting socio-economic descriptions were overlaid

onto Baringo County AEZ, soils and land use maps to visualise patterns that would inform specification of

the target geographical indication region. The results show that GIS is an important tool to inform

production decisions and policy making on geographical regions of origin based on natural as well as socio-

economic data.

Habitat use by black rhinoceros in Ruma National Park Susan Anyango Oginah

In Kenya, the population of black rhinoceros declined by nearly 98% between 1970 and 1990. Between

2011 and 2012 Kenya Wildlife Service re-introduced twenty-one black rhinoceros to Ruma National Park.

However, conservation translocation is a complex process that does not, for instance, end with the release

of translocated individuals. Understanding habitat use by translocated individuals is an important

component in monitoring success of translocation. For the case of Ruma National Park, however, habitat

use including preference has not been investigated due to resource and personnel constraints. The goal

of this study was to investigate habitat use by the translocated population. In order to do so, GIS

techniques and standard ecological techniques were employed. In brief, training data was used to

characterize vegetation types. Using fishnet method in Qgis, thirty habitat points were regularly selected

measuring 2 km apart. Rhinoceros selection of each habitat plot was determined by counting rhinoceros

prunes. The data allowed us to map vegetation types preferred by black rhinoceros and habitat-use by

the population more generally. Findings from the study provide key baseline data for management of the

species both in Ruma National Park and may inform the meta-population approach in conserving this

critically endangered species.

Paper Session 2: Current Technology Trends

Analysis of Drill Hole Data to Maximize Drilling Investment Geosoft has made it easier and simpler for geothermal and geological exploration working within Esri

ArcGIS. Explorers, geologists and mining engineers can visualize drill hole and borehole geology data and

quickly integrate it with their exploration data without leaving their ArcGIS environment. Tight integration

between Geosoft and Esri ArcGIS platform can now ensure easy sharing of data, results and knowledge

between both exploration and GIS environments.

Use of target for ArcGIS extension for ArcGIS to simplify 3D visualization and conduct integrated analysis

of drill holes and borehole geological data with ArcMap to enhance subsurface insight which is needed

during mine development.

Integrated borehole positions with geology, geochemistry or geophysics data through plan, profiles and

section map views present geological, geochemical, geophysical and geotechnical data in a single graphic

display and create a new streamlined workflow making it easy to digitize geological interpretations on

section maps using the native ArcGIS editing tools thereby helping save all your interpretations to a single

interpretation Geodatabase, making it easier to manage and to share geological models with colleagues

and different platforms. Interpretation of subsurface information is also simplified.

Exploratory drilling is essential for determining if a geothermal reservoir is capable of producing sufficient

hydrothermal fluids for power generation or economic determination of a reserve. Exploratory drilling is

used for building accurate reservoir models based on hard evidence from what is observed down hole, it

also help define reservoir boundaries, estimate production potentials, characterize the subsurface

geology, and provide essential fluid geochemical data and therefore clear visualization for interpretation

at greater insights is needed made possible by Geosoft extension for ArcGIS for use in companies doing

exploration and drilling such as Geothermal Development Company(KENGEN) and other mining or

exploration companies or firms.

Remote Sensing/Gis Software Utilization and Challenges – An Exploratory Study In Nigeria Asiyanbola Raimi Abidemi, Department of Geography, Faculty of Social Sciences, Osun State University, Osogbo, Osun State, Nigeria. Email: siyraimi@yahoo.com, Phone Number: +234 8056206690

The paper is an exploratory study of the use of Remote Sensing/GIS Software particularly by the

researchers in tertiary institutions and utilization challenges by the urban managers in Nigeria. Among the

questions addressed in the paper are: What are the broad areas of research and topics that are

addressed? What type of remote sensing and GIS software are used? What are the sources of satellite

images used? What are the type of institutional affiliation and departments of the researchers? What are

the utilization challenges?

The data used in the study is from an extensive published article search on the internet and the

administration of 101 questionnaires to public servants. Descriptive statistics are used to analyze the data.

The study shows among others that most of the researches are on analysis/applications, most of the

research topics are on land use/land cover, ESRI software products are the most used products, top on

the list of problems affecting use of GIS/Remote Sensing applications is financial problems, followed by

power supply (electricity) problem, lack of knowledge about GIS/Remote Sensing applications, lack of

incentives/motivation, and technical nature of the applications. Policy implications of the findings are

discussed in the paper.

Vulnerability of Groundwater to Pollution: Locating Pollution Hot Spots in the Lake

Nakuru Drainage Basin Simon M. Onywere Kenyatta University, Kenya Onywere.simon@ku.ac.ke The East Rift System in Kenya is formed by near N-S elongate and distinctly recognizable block structures detached from the main bounding faults; Elgeyo Detachment; Aberdare/Sattima Detachment and Nguruman Detachment. The faulted central basin of Nakuru-Elmenteita-Naivasha basin sits in the Aberdare/Sattima Detachment. Lake Nakuru area, the focus of this study lies in a graben between Lion Hill fracture zone and a series of step fault scarps leading to the Mau Escarpment. The lake is elongate in the N-S direction and dammed to the north by Menengai caldera. It is a shallow soda lake, rich in algae, the source of food for millions of flamingos that are an attraction to tourists visiting the country. The recharge to the lake is mainly by rainfall and increments from the surface runoff from Enjoro, Makalia, Larmudiac and Enderit rivers that drain the Mau. Sustainability of the hydrology of the Lake Nakuru Drainage Basin as an ecosystem and as a source of groundwater supply to the community has over the years raised concern due to: land use, settlement trends, urbanization, land degradation and waste management and their impact; and lake and community vulnerability to impacts from surface and

groundwater pollution. Because of the porous nature of the pumice and ash formations in the catchment area and the presence of fault fractured zones the surface runoff sinks into the ground before reaching the main streams or the lake itself. The poorly consolidated soils are largely exposed leading to increased surface runoff and soil erosion. In a sampling survey for water quality analysis of 22 boreholes, 2 springs and 10 raw surface waters from the area. Most of the water samples showed measured values much higher than the standard for drinking water. Two borehole samples from Kwa-Rhoda; one directly on the bath of a fault line passing through Kyoto Waste Dumpsite and the other one kilometre away and on the upthrow side of the fault showed: pH - Value 8.75 and 7.12 (6.0-8.5), Conductivity - 3420.0 and 1528.0 µs/cm (300), Pb - 0.711 and 0.192 mg/L (0.05), Cl - 667.0 and 87.0 mg/L (250), F - 14.0 and 9.8mg/L (2) respectively against the standard. The results show highly contaminated water especially for that sourced from within the fault line and which is a source of human health concerns. Pollution levels in Lake Nakuru from urban and industrial waste discharge are impacting on the Lake and its biodiversity. The problem was further compounded by the recent rift valley lake level rise that saw the lake Increasing its flood area from a low area of 31.8 Km² in January 2010 to a high of 54.67 Km² in Sept 2013, an increase of 22.87 Km² (71.92% by area) as evidenced from time series Landsat ETM and Aster image analysis. The flooding and submergence compromised the environmental integrity of the lake and its resources. Key words: Block detachment, hydrology, degradation, water quality, time series, lake level rise

Spatial Analysis of Land Use Development Dynamics Within Kenya’s Public Universities in

the Devolved Framework Kinoti Kibetu Department of Arts and Humanities, Chuka University P.O BOX 109, Chuka, Kinotikibetu@yahoo.com 0723 683 831 University land use development is influenced by policy implementation. Establishment of universities is

driving urbanisation and ecological transformations. Currently there are no studies on the role of

development planning policies on universities land use and resource utilisation. To bridge this gap, the

study sought to analyse the implications of the changing Land Use and Land Cover around Chuka and

Karatina Universities Main campuses. Land use and cover change was taken as proxy to land development

within and around the campuses. To effectively address this objective the study used GIS and remote

sensing to analyse the dynamic interactions between the different aspects of the historical and present

land uses between 2003 and 2015. Findings from the two case studies revealed that land use is directly

influenced by university management councils and guided by the national land policy framework. The

different administration and development policies adopted by the two university managements resulted

to land use patterns variations observed across the sampled campuses

Assessment of Seasonal Malaria Episodes in Malindi Sub- County Bertha Othoche, Pwani University, Department of Environmental Science; P.O Box 195, Code: 80108, Kilifi

Application of geospatial tools in monitoring environmental health cannot be understated. Monitoring

disease vectors is a significant undertaking not only in the health sector but also in medical geography

and in other epidemiological studies. Malindi Sub-County lies within malaria endemic region in the

coastal belt of Kenya. Malaria outbreak is closely associated with seasonal weather and climate

patterns. Climate change occurs when the elements of climate show marked departure from long term

average values. Such changes may have impacts on environmental health. In Malindi sub-county,

disease vectors have been prevalent in different seasons in varying densities. The prevalence of

mosquitoes according to weather changes has been established. Mosquitoes in turn spread malaria

resulting in increased or seasonal patterns of confirmed or clinical malaria. The study uses longitudinal

data from Msabaha weather station and from five specific hospitals and dispensaries in the study area

to establish relationships between weather patterns and malaria outbreak. Global Positioning Systems,

(GPS) is used to establish the spatial characteristics of environments associated with malaria

epidemiology in specific ecosystems in Malindi Sub-County. The data is fed into the GIS environment for

mapping. The results are then analyzed to establish correlations and recommendations made based on

the results
